Properties of matter
Anything that has mass and takes up space is called this.
What is matter?
The three most common states of matter are solid, liquid, and blank
What is gas?
The smallest part of an element that still has the properties of that element.
What is an Atom?
This element is what we breathe in to stay alive.
What is oxygen?
The molecule we breathe out when we exhale is made of one carbon atom and two oxygen atoms.
What is carbon dioxide (CO₂)?
This is how much space an object takes up.
What is volume?
This state of matter has a definite shape and volume.
What is a solid?
These are the tiny building blocks of matter.
What are atoms?
The simplest type of pure substance, made of only one kind of atom.
What is an element?
When two or more types atoms join together, they form this.
What is a molecule?
This is how much matter is in an object.
what is mass?
The particles in this state of matter are close together but can slide past each other.
What is a liquid?
atoms are made of protons, neutrons, and these negatively charged particles.
What are electrons?
The chart that shows all the known elements is called this.
What is the Periodic Table?
Two hydrogen atoms and one oxygen atom make this molecule.
What is water (H₂O)?
A property that can be observed or measured without changing the substance’s identity, such as density, melting point, or solubility.
What is a physical property?
When a liquid loses heating energy, this change of state happens.
What is freezing?
The center of an atom, where protons and neutrons are found.
What is the nucleus?
Oxygen, hydrogen, and carbon are examples of these.
What are elements?
A substance made of two or more different elements chemically combined.
What is a compound?
A property that describes a substance’s ability to change into a new substance through a chemical reaction, such as flammability, reactivity with acid, or ability to rust.
What is a chemical property?
Matter changes from a liquid to a gas gaining heat energy during this process
What is evaporation or boiling ?
Even though atoms are extremely small, the way they are arranged and connected determines the different physical and chemical properties of substances.
What is structure of matter (or how atoms make up substances)?
Water and salt are not elements because they can be broken down into simpler substances. Elements are different because they are always made of only this.
What is one kind of atom
This is the term for the force that holds atoms together in a molecule.
What is a chemical bond?
